摘要： The present invention relates to a pre-passivation process for a continuous reforming apparatus prior to the reaction, or a passivation process for a continuous reforming apparatus during the initial reaction, comprising loading a reforming catalyst into the continuous reforming apparatus, starting the gas circulation and raising the temperature of a reactor, injecting sulfide into the gas at a reactor temperature ranging from 100-650° C., controlling the sulfur amount in the recycle gas within a range of 0.5-100×10−6 L/L so as to passivate the apparatus.The process of the present invention may also comprise the following steps: (1) loading a reforming catalyst into the continuous reforming apparatus, starting the gas circulation and raising the temperature of a reactor, feeding the reforming feedstock into the reaction system when the temperature of the reactor is increased to 300-460° C., introducing sulfide into the reaction system while or after the reforming feedstock is fed, controlling the ratio of the total sulfur amount introduced into the system to the reforming feedstock within the range of 0.5 μg/g-50 μg/g, reducing the content of sulfide introduced into the system when hydrogen sulfide concentration in the recycle gas reaches to 2.0 μL/L˜30 μL/L; and (2) maintaining the reforming reactor at a temperature of 460-490° C., controlling the ratio of the total sulfur amount introduced into the system to the reforming feedstock within the range of 0.2 μg/g-0.5 μg/g, adjusting the amount of the reforming feedstock to the design value of the apparatus, increasing the reforming reaction temperature to 490-545° C. according to the requirements on the octane number of the liquid product, and letting the reforming apparatus run under normal operating conditions.
